See your eye doctor: For your symptoms of floaters you should see your eye doctor right away to see if it's the sign of a serious problem. As for your other symptoms, they should warrant some further testing.
I believe that it is correct to say that RNA is not replicated, but reproduced. DNA, what I know currently, is the only one that replicates itself.   Plus, to my knowledge, you don't need to copy a RNA strand.
Where and when do replication, transcription and translation occur in the eukaryotic cell Replication and transcription occur in the nucleus Translation occurs in the cytoplasm In addition, the RNA in eukaryotic cells goes through a processing step before it can be transported out of the nucleus.
